The radial coils 8 are so Wound as to e0 incide at their outer marginsWith the inner curvature of the tire being of increasing diameter fromtheir inner terminals to a point coinciding with the horizontal diameterof the tire. As Will be seen the structure and arrangement of thesprings is such that the cavity or bore of the tire is relatively filledby the snrings; The springs 8 are not however composed of circularcoils, but are i oval 0r obloid transversely oil the circle de- Thus thespring conformsfined by the tire, and the tire will thereforeaccommodate a multiplicity of coils, ar-

ranged at close intervals whereby the tire is cushioned at all of itsparts, subject to com pression or distortion.

As shown in i i 7, the radial springs may be bent so as to form coils ofsubstantially rectangular shape by which means their points of Contactwith the tire Will be of greater area, and more effective than Where thecontact is obtained through a curved part of a spring. I

What I claim as new is A cusl'iioning device for resilient hollow tirescomprising an interior, circumferentially arranged spiral spring havingindentations in its coils, and a series of radial springs havingdiametrically arranged terminal eontinuations fittingsaid indentationsand interlocking the partstogether.

In testimony whereof I afiix my signature.
